TOPSHOTS Kenyan men with buckets of water work to put out a fire caused by an electrical fault from one of the residences, as it razes houses in Deep Sea slum in Nairobi on April 9, 2014. There is a high risk of fire in Nairobi's slums and informal settlements due to the homes being poorly constructed and the materials used of inferior quality. In addition, people live in overcrowded conditions, and electricital connections, where they exist, are often unsafe. AFP PHOTO / SIMON MAINA
